PHP Update script.. filemtime? -

i sort of beginner php , trying make script shows, in file can include on side part of index page, date of last update , plus underneath list of other pages have updated (in order of update). example if last time updated tuesday , edited news , index page say

august 6, 2013 - home page updated. - news headlines updated.

then underneath show other latest updates.. so:

august 6, 2013 - home page updated. - news headlines updated.

august 5, 2013 - staff updated.

august 2, 2013 - home page updated. - forum updated. - join page updated.

i able set limit on how many updates can shown.. had friend had script years ago , remember done through .txt file , chmod txt file have written permissions. updates.php , on every page wanted generate update status include few lines of scripting @ top of file.. plus list page names , wanted show in either txt file or updates file index.php > home page updated... have lost contact him , no way of me finding it. had go , and got:

  <?php    $pages = array(   'main page' => 'index3.php',   'staff' => 'staff.php',   'news headlines' => 'news.php',   ); $list = array();   foreach($pages $page => $file) {   $date = filemtime($file);      if(!isset($list[$date])) { $list[$date] = array(); }   array_push($list[$date], $page);   }  krsort($list);   foreach($list $date => $pages) {   echo date('f j, y', $date) . "<br />\n";    foreach($pages $page) {     echo "- $page updated<br />\n";     }       }    ?> 

but doesn't work correctly starts new date if update 2 files in same day... anyway wondering if had idea of how make script? in desperate need great.. unsure of how go , have looked everywhere ages ideas... people , hope hear :)

filemtime() return unix timestamp, 2 updates in same day still 2 different timestamps. instead of using date() format date when echo it, format before saving $date variable:

foreach($pages $page => $file) {   $date = date('y/m/d', filemtime($file)); 

then when print out:

echo date('f j, y', strtotime($date)) . "<br />\n";
